model p52937 video in plug is loose, when plugging in screen goes blank. If I wiggle it it comes on then goes off again. Is it a short or something?


What usually happens is the solder connection at the circuit board where the video jack is soldered to the board has developed a crack around the connection.
A very common problem caused by the force of repeated
inserting and removing the video cable. This can be easily fixed with a soldering iron and some solder.
If you don't have experience with these tools have someone qualified repair it for you. You would be looking at no more than 1 hour labor and no parts.

No speaker sound


Unfortunately, these small jacks are not very durable.
They can be constructed to turn off internal speakers when a plug is inserted into the jack or not. There are normally small bumps on contacts in the jack that are pressed upon when inserting the plug and if their spring qualities are less than good, they stay somewhat bent after the plug is removed leaving one or more channels dead.
The cost of a replacement jack is miniscule (any electronic supply that caters to hobbiests will have them) but the replacement may require extreme care. The jack could be a board-mount type with angled leads that are inserted through the board or could be attached by thin wires. With care, the board mount type is the neatest to replace but one should have some soldering skills and a good iron to avoid damaging the circuit board. The wired type makes a messy repair and demands even more skill to keep stray wires from shorting each other and one always risks breaking the thin conductors while handling them.
